Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Yes. If you put water and hexane in a beaker or a container together, the hexane will be on top of the water. One way to see this is to dye the water. They do not mix because water is polar and the hexane cannot dissolve in it. It is on top because, guess why? It is less dense than water. That is why anything floats on water... it is less dense! Hope that answers your question!
Thanks for the feedback!

Does hexane float or sink in water?

  Hexane is less dense than water and is not miscible-- therefore, it floats.

Hexane solube in water?

NO Hexane will phase separate when added to water. The hexane will form the top layer , as it is lighter than water

Is hexane soluble in water?

No hexane is insoluble in water. "Like dissolves like" meaning the more alike (chemically) two things are the more likely they will be soluble in each other. Hexane and water

Does hexane and bromine water and sodium hydroxide solution react?

  If this is supposed to be an alkene test, then no, hexane will not react with bromine water to take away its color as it is an alkane and therefore contains no double bo

Does hexane burn in oxygen gas to form carbon dioxide gas and water vapor?

Yes*. The empirical equation for this reaction is: 2C6H14 + 19O2 ---> 12CO2 + 14H2O. * n-Hexane, burned in an Iron III-catalyzed environment of pure oxygen gas, is oxidize

What is hexene and hexane?

No. They have different molecular formulas. Hexane (C6H12) and Hexene (C6H10) because of the double bond.

Is hexane is toxic?

yes it is.

Why does hexane separate from water?

Hexane separated and don't mixed with water because water is polar and hexane is non polar so it cannot dissolve in it.

Why is ethanol soluble in water and hexane?

Ethanol is soluble in water because the -OH group of ethanol (CH3CH2OH) can form hydrogen bonds with water. Hydrogen bonding occurs when a very electronegative molecule like O

Why mineral oil dissolve in hexane and not in water?

  Polar substances are miscible (will dissolve) in each other and non-polar substances will dissolve in each other. "Like dissolves like!" Mineral oil is non-polar. Hexane
